Another game was released for the Sony PlayStation 2 by Atari; simply titled as Transformers, it was based on The Transformers: Armada. The game's reception was mixed, particularly due to the popularity of a PS2 Transformers game released at the same time for a Japanese-exclusive market, though the Armada game was of a higher quality and featured much better gameplay. The game not released in America was based on the Generation 1 storylines.
Scarlett later used the Brainwave Scanner to contact Optimus's spirit and guide him back to the mortal realm. In the physical world, Ultra Magnus challenged Megatron to a duel on a Dyson sphere surrounding the sun. The Autobot god had not ferried Optimus to the afterlife - he had merely repaired Optimus's body by taking it into himself. During the climatic duel, he allowed Optimus to burst free from within his armor. The reborn Optimus punched Megatron into the sun, then turned his attention to reclaiming the stolen Matrix from the Decepticons. After Atlas defeated the maddened Primus, Optimus healed Snake-Eyes' injuries. Optimus then turned his attention to returning Primus/Cybertron to its regular orbit. As the planet left the solar system, he departed aboard the Ark 2 alongside a crew of Joes and Autobots, in the hopes of contacting the Makers. The War Never Ends
While Transformers ended poorly for the US market, the same can not be said for the UK, Canada, and Japan markets as they went on to produce their own continuing series between 1991 and 1993, despite the UK market in particular missing a substantial amount of figures prominent in the comics and animated series throughout the line's run. Each country produced their own continuity. The UK and Canada continued with new Action Master figures and introduced the Turbo Masters and Predators. Japan continued with the Micromasters concept.
While the other Autobots searched for the Matrix on Earth, Optimus Prime searched for Vector Sigma, guided through the dangers of the planet's catacombs by the spirit of Alpha Trion. Prime eventually arrived at the computer, only to find his way barred by Cyclonus and Scourge. At that moment, Hot Rod arrived with the Matrix, the same with which Alpha Trion merged, re-energizing it. The Matrix transformed Hot Rod back into Rodimus Prime and, for the first time, the two Primes fought side-by-side and defeated Galvatron. Before Rodimus could implement the Matrix to stabilize Vector Sigma, however, Optimus Prime merged himself with the computer, restoring its balance to save the planet. Optimus Prime sacrificed himself, dying again only a few short episodes after his rebirth. Later, Prime would make a final and permanent return in the Japanese Transformers continuity, Battlestars: Return of Convoy. This entry was only available in print, appearing in the TV Magazine, a Japanese publication.

A redeco of Cybertronian Optimus Prime with a translucent red front section, additional (painted) "scratched paint" details, some red paint highlights either omitted or changed to yellow and additional yellow circuitry pattern detailing reminiscent of the jammed abilities/mode lock/EMP effect from the War for Cybertron game, available in a Toys"R"Us-exclusive three-pack with redecos of Cybertronian Megatron and Cybertronian Bumblebee.

Released as part of TakaraTomy's Transformers Movie The Best toyline to conclude the 10th anniversary of the live-action film series, this Optimus Prime is an extensive redeco of his Evasion mode toy. He also uses the faceplated head and the dark gray-colored Ion Cannon used for the Evolution 2-pack/Platinum Edition 5-pack release. While his deco had taken cues from both the TakaraTomy release of Evasion Mode Optimus Prime and the Platinum Edition Breakout Battle figure, the weathering pattern bears a similar resemblance to his rusty version of the figure. Unfortunately, this release suffers from heavy mold degradation, particularly in the form of ill-fitting tabs around the truck front/shoulder area.
While the Transformers animated series came to an end in America in 1987 after The Rebirth, production was continued in Japan with three new, exclusive animated series spin-offs to continue the story. The first of these series, Transformers: The Headmasters, supplanted the events of The Rebirth. With the Decepticons defeated, the Autobots entered into an even closer relationship with Earth. The Autobots also began the colonization of other worlds, the first of which was the planet Athenia, where Optimus Prime was stationed. It soon became apparent, however, that the consequences of releasing the energy of the Matrix to cure the Hate Plague were more far-reaching than Optimus had anticipated. Without the energy of the Matrix to act as a balancing factor, Vector Sigma had become destabilized. The Decepticons suddenly returned to exploit this, assaulting Cybertron in order to seize control of the mega-computer. Prime took a squad of troops to aid in the battle on the planet. When the arrival of the Autobot Headmasters tipped the battle in their favor, Prime broke off from the main attack and headed down into the depths of the planet, planning on stabilizing Vector Sigma at any cost.

IDW's Transformers Collectors Club exclusive comic story, Revelations part 6, is set after the defeat of Galvatron, but before Optimus Prime's mission to start a new Space Bridge project. In this story, the Autobots from the IDW series Robots in Disguise, Optimus Prime, Ultra Magnus, Sentinel Maximus, Downshift, Perceptor, Alpha Trion, Over-Run, Anti-Blaze, Checkpoint, and Scythe, meet the Autobots from the animated series, Cybertron Optimus Prime, Jetfire, Override, Scattorshot, Red Alert, Hot Shot, Lori, Bud, and Coby Hansen, and thank each other and remembering those who were lost in the battles.[40]

Optimus appears again in the 2011 film Transformers: Dark of the Moon. Optimus receives his own armory consisting of weapons and flight tech that transforms into a trailer for him to carry in vehicular form. After assisting NEST operatives in fighting Shockwave at Chernobyl, Optimus learns that the humans have concealed the discovery of a Cybertronian ship on the moon. He and Ratchet go to investigate the Ark, where they recover Sentinel Prime, Optimus's predecessor and mentor. Optimus returns him to life using the Matrix of Leadership back on Earth, explaining how they lost the war and Cybertron has become a barren wasteland. Later Optimus shows Sentinel the natural beauty of Earth, and takes the opportunity to offer him the Matrix, but was allowed to keep it. Sentinel later betrayed the Autobots, having formed an alliance with the Decepticons because he wants to restore life to Cybertron. Optimus attempted to reason with Sentinel, but failed as several Decepticons came through a space bridge. After Sentinel Prime insisted that the humans expel the Autobots from Earth, the Wreckers prepare the Autobot ship Xantium for flight. Sam attempts to find out what their counter-attack plan is, but Optimus states they have none, and that Earth's fight is their own. During the departure, the Autobots escape in the first booster stage and return to Earth before Starscream destroys the ship. Arriving in Chicago, Optimus shoots down a Decepticon fighter as he tells Sam and Epps that he never expected the Decepticons to keep their word and that they are going to fight back. Optimus loses his trailer when Shockwave and his Driller arrive. He manages to retrieve it later and uses it as a flight pack, decaptitating the Driller's main head. During the battle, Optimus got caught in exposed wires and the Wreckers helped free him. Flying down onto the main battlefield, he abandoned his flight pack and used the momentum to attack and kill many Decepticons before he finally killed Shockwave. After using Shockwave's cannon to disable the control pillar for the space bridge, Optimus fights Sentinel Prime. Optimus Prime's right arm is cut off and Sentinel is about to end Optimus's life when Megatron intervenes and attacks Sentinel. After defeating Sentinel Prime, Megatron proposes a truce, but, instead, Optimus slices his head off, killing the Decepticon leader. Optimus Prime then grabs Megatron's shotgun and prepares to execute Sentinel, who pleads for his life, saying that he betrayed Optimus just because he wanted to save their race. Optimus executes him anyway, replying that Sentinel betrayed himself. With the Decepticons defeated and the war finally over, Optimus and the Autobots accept Earth as their true home.
Aside from the Powermaster feature itself, the main gimmick of the toy is the ability of the truck cab to combine with the trailer to form the larger "Super Optimus Prime" figure. This is essentially accomplished by standing the trailer up, folding the cab in half and inserting it into the empty cavity in the trailer's torso, forming an imposing—if almost entirely unposeable—robot form armed with all four weapons. The head of this super robot form is a separate piece which can be stored in the rear of Prime's trailer when not in use. While Hi-Q was always shown plugged into Prime's chest in artwork of this mode (as seen in the picture here), this was actually entirely unnecessary as transforming into Super Optimus Prime didn't require the standard Prime toy's legs to be unlocked.
That’s actually a very big part, but I’d go lower than the $10 sets. The little tiny box sets with one minifig and some small vehicle or accessory that were $1-4 when I was growing up in the 80s now seem to be anywhere from $5 to $12 on the shelves. The cheapest of those are the sets that you could buy as a casual gift with pocket change in the 80s. Related to that, I’d like to see a metric that tracked the bottom price (both sticker price and adjusted price) of sets each year.

The all new 2006-2007 Classics line featured characters from the original series in updated forms. Hot Rod (now called Rodimus due to trademark reasons) was in the first wave of Autobots along with Optimus Prime and Bumblebee. Due to most of the Classics lacking visible Autobot and Decepticon insignias, this figure lacks the distinctive Autobot symbol seen on the chest of all other versions of Hot Rod/Rodimus, to which fan companies have responded to with alternative stickers. His vehicle mode is based on an obscure Japanese Supercar, the Dome Zero, manufactured by DOME Co. Ltd in 1978.[citation needed]

On a mission with the Triggerbots to stop Megatron from claiming the Underbase, Prime was forced to jettison the massive databank into space to prevent anyone from acquiring its power. With this action, he proved his wisdom and skill to the Autobot Council of Elders. He continued to move up in rank, eventually becoming the field command over the Autobot armies.
When they could not reanimate him, they used his body as a lure instead, bringing the Autobots to their lab, where they are infected. As this "Hate Plague" began to spread across the galaxy, Sky Lynx retrieved a Quintesson, who fully restored Optimus Prime to life. Coating himself in Morgan's heat-resistant alloy, Prime reclaimed the Matrix from Rodimus and unleashed its concentrated wisdom to destroy the Hate Plague.

Available exclusively at the Tokyo Toy Show 2012 (along with Prime Shining Optimus Prime), Black Optimus Prime is a very minor redeco of the previously unreleased Gentei! Gentei! black version of Henkei! Henkei! Convoy, itself a redeco of the Classics Voyager Class toy. As such, Black Optimus Prime is mostly cast in black plastic, with some gray parts, translucent red windows and teal paint operations.

Hot Rod then fought in the battle of Autobot City and saved the city for if he had not attacked Megatron, he would have destroyed it. Due to his attempted intervention in the epic battle between the Autobot leader, Optimus Prime and the Decepticon leader, Megatron, Prime was lethally injured. Before he died, the Matrix got passed on to the Autobot Ultra Magnus, whom he referred to as "old friend", despite protestations.
